TL;DR: This paper outlines a new architecture, the Active Memory Cube, which reduces the energy of computation significantly by performing computation in the memory module, rather than moving data through large memory hierarchies to the processor core.
Patent
Ultrascalable petaflop parallel supercomputer

TL;DR: In this paper, a massively parallel supercomputer of petaOPS-scale includes node architectures based upon System-On-a-Chip technology, where each processing node comprises a single Application Specific Integrated Circuit (ASIC) having up to four processing elements.
Patent
Local rollback for fault-tolerance in parallel computing systems
Matthias A. Blumrich,Dong Chen,Alan Gara,Mark E. Giampapa,Philip Heidelberger,Martin Ohmacht,Burkhard Steinmacher-Burow,Krishnan Sugavanam +7 more
TL;DR: In this paper, a control logic device performs a local rollback in a parallel super computing system and checks whether an error occurs during the rollback interval, if the error occurs and the unrecoverable condition does not occur.
